I majored in mathematics and computer science as an undergraduate (along
with a minor in English Literature). I studied computer mathematics
and numerical analysis in graduate school.

I began writing and improving existing statistical and numerical software in
1970. Until 1985 such statistical software development activities
comprised a major portion of my duties, first at the University of Illinois
at Chicago, and later at Northwestern University. During this period I
wrote some major components for SPSS (e.g., SPSS MANOVA) and SCA. I also
ported and improved a wide variety of statistical programs to Control Data
mainframes.

In December of 1988 I left Northwestern University to join a start-up
firm, Reflective Systems. We sought to meld artificial intelligence
techniques, database methods, and network access into a seamless approach to
accessing distributed data, discovering hidden data relationships, and
producing concise reports in written and graphical form. The system we
envisioned also incorporated advanced techniques for guiding data
analysis. Unfortunately, we were not able to attract sufficient funding
to take our ideas further than a prototype system.

After Reflective Systems closed in 1990, I joined another startup,
Broadview Communications, which sought to develop leading-edge communications
software for PCs.

In the Fall of 1993 I returned to Northwestern University. I have not
worked on statistical computing applications since 1990. I miss this
line of work since it was a big part of my professional career for so many
years.
